Y = x-3
Basically you just need to plug in an x value and solve for y
y = x - 3
y = (4) - 3
y = 1
In this case, the ordered pair of this equation would be (4, 1)
You can do this given any x or y coordinate
Hope this helps
Answer:
The price is x = $2.779
Step-by-step explanation:
From the question we are told that
The revenue is 
The cost of production is 
Generally at break even point the cost of production is equal to the revenue
So

=> 
Using the quadratic formula to solve this equation we have that
x = $2.779
